## Reflection: Advanced Students Complements of 10 - Section 2: Introducing Complements of 10 With 10 Frame Cards

It is important to know your students abilities.  In this case, there is no point to have students who are secure with their complements of ten to participate in the 10's game.  However, the expectation is that students can use their knowledge of 10 to solve for 20 (by the end of first grade).  The 20's game will allow for this practice and application of that skill.
